SIX-WHEEL-TRUCK CONSTRUCTION.

Application filed January 28, 1923. Serial No. 615,082.

To all whom it may concern:

Be it known that we, CLAUDE L. ORR, JACOB O. LARSEN, and GEORGE T. JOHNSON, citizens of the United States, and residents of Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Six-VVheeL Truck Construction; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to car trucks of the sixwheel type and has special reference to the manner of mounting the side bearings. One object of the present invention is to so mount the side bearing that it will interlock with the center and longitudinal bolsters and prevent separation of the same, and another Object is to provide a side bearing which may be easily adjusted to compensate for wear, and which will be held in its proper position without the use of rivets, bolts, or other fastening devices. Other objects will appear incidentally in the course of the following description and the invention resides in certain novel features which will be particularly pointed out in the appended claims.

In the accompanying drawings, which illustrate one embodiment of the invention, Figure 1 is a plan view of a truck with the side bearings in place,

Figure 2 is a view partly in side elevation and partly in longitudinal section on the line 2-2 of Fig. 1,

Figure 3 is a transverse section on the line 33 of Fig. 1.

In the drawings, the reference numeral 1 indicates the car wheels having their axles carried by journal boxes 2 which are mounted in the end and central member of the side frames 3 of the truck. The end members of the side frames are constructed to provide seats 4 for the springs 5 upon which rest the ends of the end transverse bolsters 6 which are constructed with guide lugs 7 on their sides to engage the inner and outer faces of the side frames whereby the separation of the bolsters and the side frames will be prevented while flexibility is retained, it being noted as shown most clearly in Fig. 2, that the lower portions of the spring and bolster receiving openings are somewhat sters 8 are disposed at opposite sides of the center of the truck and are provided at their ends with depending keeper and guide brackets 9 which embrace the transverse bolsters between guide lugs 10 thereon whereby lateral movement of the longitudinal bolsters will be prevented but vertical movement is permitted thereby providing the desired flexibility in the truck and maintaining the longitudinal bolsters upon the transverse bolsters without the use of bolts, rivets or similar devices. The center bolster 11 is carried at its ends by the longitudinal bolsters which are expanded vertically at their centers, as shown in Figures 2 and 3, and constructed with transverse openings 12 through which the ends of the center bolster are inserted. The extremities of the center bolster project outwardly beyond the respectively adjacent longitudinal bolsters and on their upper sides are formed with cups or sockets 13 while on the outer sides of the longitudinal bolsters are keeper loops 14 above and alined vertically with the cups or sockets 13. The keeper loops are open at both their upper and lower ends and their contour conforms to the particular form or type of side hearing which is to be used, being shown in Figure 1 as oblong in form. The bearing block 15 fits snugly within the upper end of the keeper 1d and is supported therein by a filler 16 which is provided on its lower end with a stud or tenon 17 to fit within the cup or socket 13 and thereby bring the parts into the proper assembled relation, a shim 18 being interposed between the filler and the bearing if needed. I Shims may also be employed between the lower end of the filler block 16 and the top of the boss defining the cup or socket 13.

It will be readily noted that by the present invention, the side bearing block is held in position securely without the use of rivets, bolts or other fastening devices. and also constitutes means for locking the longitudinal bolster to the center bolster so as to prevent displacement of either bolster without reducing the flexibility of the truck in anyway.

Having fully described our invention what we claim as new and desire to secure by Letters Patent, is

1. In a, car truck, the combination of a longitudinal bolster, a center bolster, and a side bearing supported on one bolster and engaged with the other bolster.

2. In a car'truck, the; combination of a center bolster, a longitudinal bolster supporting the end of the center bolster, a side bearing, and means whereby the side bearing will lock the bolsters together.

3. In a car truck, the combination of a center bolster, a longitudinal bolster, a side bearing supported on one bolster, and a keeper loop on the other bolster engaging around the side bearing.

4. In a car truck, the combination of a center bolster, a longitudinal bolster, a side bearing supported on the centerbolster, and a; keeper loop on the side of the longitudinal bolster engaging around the side bearing.

5. In a car truck, the combination of a longitudinal bolster, a center bolster having its end extending through and supported by the longitudinal bolster, a side bearing supported by the end of the center bolster at the outer side of the longitudinal bolster, and a keeper loop on the side of the longitudinal bolster engaging around the side bearing.

6. In a car truck, the combination of a longitudinal bolster, a center bolster having its end supported by the longitudinal bolster, one of the bolsters being provided with a socket, a keeper loop on the other bolster alined with the socket, a filler having its lower end engaged with the said socket and its upper end fitting in the lower end of the keeper; loop, and a side bearing block fitting in the upper end of the keeper loop and supported by the filler.

In testimony whereof, we have signed this specification in the presence of two subscribing witnesses.
